This study will explore the effect of clopidogrel on coated-platelets in patients who are
given an loading dose before diagnostic catheterization or percutaneous coronary
intervention. We hypothesis that clopidogrel will reduce the percentage of platelets that
are coated and therefore more hypercoagulable.
- Patients given clopidogrel loading dose before scheduled catheterization or
- Acute coronary syndrome
- Unable to tolerate clopidogrel
